ROBINSON BUTTER, OF VALLEJO, CALIFORNIA.

Letters Patent No. 103,780, dated May 31, 1870.

IMPROVEMENT IN NUT-LOCKING- WASHERS.

The Schedule referred to in these Letters Patent and making part of thesame.

I, Romnsou BUTTER, civil engineer, of Vallejo, and-State of California,have invented certain new and useful Improvements inthe construction andarrang'ement. of- Fish-Platcs'for, Rail-Joints; also,

straps for fish-plates, which I have designated the will beflfs'e'en, toreceive the tampingof the washers when screwed up tight against thatpart of the fish- 'plat'efi- "Section shows a side view of fish-plate,Fig. A, with the fluted out prints, as already described.

- Figure B represents also a side view of a fishplate, with six-sidedprints cast on the fish-plates, for

' washers of two inches in diameter.

The washers, when screwed up tight against its face, allow a projectionin the washer, which is bent over and hammered on and over-the edges ofthe prints, keeping the prints perfectly fast from twisting and workingloose,

Figure 0 represents a plane-faced fish-plate, except where thewashersare placed over the bolt-holes, as will be seen.

On each side there are sunk recesses to allow the projecting part of thewashers to be bent over the edges and 'tamped in.

The dotted circulars denote the washers.

Section of Figure 0 shows how the recesses are cast or cut in.

Figure D represents another face of a fish-plate, with raised lips orbeads, single, double, square, and six-sided, suitable for thebolt-heads only to rest in, which prevents the bolts from turning roundwhen being screwed up, or after.

The lips are cast on and project out one-fourth, threeeighths, orone-half an inch.

The second part of my invention relates to the Iock-'straps,-which areplaced on the face of any plainfaced fish-plates now in use.

The lock-straps are two in number; one for the heads of the bolts, theother for the nuts of the bolts. They both pass over two holes whenfixed upon the fish-plates.

Figure 1 shows the side view for the bolt-head side, with raised lips orbeads cast onto the lock-strap. The holes are a little oblong to admitof expansion and contraction. I

Section of fig. 1 gives a side view, full size. The

lips can be raised to one inch in depth, and of malleableized castings.Figure 5 represents the iock-strap for the nuts oi the bolts, fluted onthat circular part to tame the washers'into when screwed tight up.. I

Section, fig. 5, is a side view of'fig. 5, and showshow it is fluted outto receive tampmg of washers.

Figure 15 represents another lock-strap, showing how the washer can behammered over the edges of the six sides to keep them immovable whenscrewed up.

Fig. 15 refers to figure 14, as also figs. 14 and 15 show the side view,fulisize, of straps.

The third part of my invention refers to lip wash ers, orbeads,withsuitable raised lips to receive boltheads, or nuts, or both, as maybe required, and is designed to apply to iron bolts of any size, and incases where screw-bolts are required and used.

Figure E represents a large washer for machinery avliere vibration andoscillation loosen the nuts and screw-bolts'of any size.

Section of Fig. E, as cut through s .9, gives a side view, with a sunkenrecess, to receive thetop washer, Fig. F, from moving out of its centerwhile, being screwed up.

- Fig. E has four, more or less, flutes hollowed-out to receive thetamping in of washer, Fig. F.

There are cast onto the sole or bottom of washer, Fig. 19-, points orstubs, to prevent it turning round whilebeing screwed up, and relates towashers of any size.

Figure F is for either the head or nut of a bolt, with raised lips to aninch deep, single, double, square, .or six sides, to receive the headsor-nuts' of any sized bolt of. iron.

Figure 3 represents a washer, or half-round strap for bolt-heads only,with a raised lip underneath for the bolt-head, to prevent it turninground, placed against the side of a plain-faced fish-plate. The

square part of this washer rests on the bottom of the rail,-and keepsthe washer from moving left or right.

Figures 7, 8, 9,.aud 10, represent washers to be used on the lock-strapsfor fish-plates, with raised lips on all sides to keep the nuts inplace, with raised lips to an inch in depth, if required.

The washers are made by the malleableized iron process, and can betamped into fluted fish-plates now in use, or can be camped into thehollows of my lock-straps, or into any of my improved fish-plates.

Figures 11, 21,'and 12 show a small sized washer, washer against whichthe nut is placed, said washer recessed and fluted out, to keep theupper washers being forced into the lock-strap, all substantially as inplace on machinery, gunnery, or bridges;

I claim as my invention The combination, in a nut-lock, of a flangedlockstrap for the head of a bolt, a grooved -01 indented look-strapfor-the screw-end of a bolt, and a flanged set forth.
